Towards a Low-SWaP 1024-beam Digital Array: A 32-beam Sub-system at 5.8 GHz
Arjuna Madanayake, Viduneth Ariyarathna, Suresh Madishetty +8
Millimeter wave communications require multibeam beamforming in order to utilize wireless channels that suffer from obstructions, path loss, and multi-path effects. Digital multibe…
Millimeter-Wave Antenna Array Diagnosis with Partial Channel State Information
George Medina, Akashdeep Singh Jida, Sravan Pulipati +5
Large antenna arrays enable directional precoding for Millimeter-Wave (mmWave) systems and provide sufficient link budget to combat the high path-loss at these frequencies. Due to…
A Passive STAR Microwave Circuit for 1-3 GHz Self-Interference Cancellation
Udara De Silva, Sravan Pulipati, Satheesh Bojja Venkatakrishnan +2
Simultaneous transmit and receive (STAR) allows full-duplex operation of a radio, which leads to doubled capacity for a given bandwidth. A circulator with high-isolation between tr…
Xilinx RF-SoC-based Digital Multi-Beam Array Processors for 28/60~GHz Wireless Testbeds
Sravan Pulipati, Viduneth Ariyarathna, Aditya Dhananjay +6
Emerging wireless applications such as 5G cellular, large intelligent surfaces (LIS), and holographic massive MIMO require antenna array processing at mm-wave frequencies with larg…
A Direct- Conversion Digital Beamforming Array Receiver with 800 MHz Channel Bandwidth at 28 GHz using Xilinx RF SoC
Sravan Pulipati, Viduneth Ariyarathna, Udara De Silva +5
This paper discusses early results associated with a fully-digital direct-conversion array receiver at 28~GHz. The proposed receiver makes use of commercial off-the-shelf (COTS) el…
